Setting of the hysteresis for the
reset of the lock.
Scaling according to DTP.
Only with setting "Threshold
comparator" and there only with
"greater than" or "less than"
comparative value
.
Behaviour during lock
no action
fixed value (one-time)
fixed value (cyclic)
Setting the behaviour of what is
to be done when activated,
during a lock
Selection
Only if "Behaviour during lock" is
set to "fixed value...".
Setting whether the height and
slats, only the slats or only the
height should be approached in
the case of a lock.
Position:
Value at lock
0 % – 100 %
[0 %]
Height position which is to be
approached during locking
Slats:
Value at lock
0 % – 100 %
[0 %]
Slat position which is to be
approached during locking
Cycle time for value
during lock
1 min – 24 h
[10 min]
Setting of the interval between
the cyclical telegrams.
Only for "fixed value (cyclic)
Behaviour after bus
power return
lock not active
lock active
restore lock
Setting the lock in the event of a
voltage recovery on the KNX bus
Table 34: Settings – Time switch: Lock object type
Lock object type
A lock can be triggered or released in three different ways:
lock object
: Lock with 1, enable with 0
enable object
: Enable with 1, lock with 0
threshold comparator
: by specifying a condition "
Lock active when
" and a
comparative value - corresponding to the "
Threshold data point type
" - a threshold is
defined from which object value the lock is triggered and, according to the set
hysteresis
,
enabled.
Important
: The hysteresis only affects the withdrawal of the lock.
Example:
Lock active when:
object value greater than comparative value
Comparative value: 10000 Lux
Hysteresis:
2%
Object value => 10001 Lux => Lock active
Only at an object value of 10000 lux - 2% (=9800 lux) is the lock withdrawn.
